A safety device for the reversible disconnection of at least one electrical component of a motor vehicle, with a first switching device. An electrical connection of a first energy supply unit of the motor vehicle to the at least one electrical component, in particular to an electric drive of the motor vehicle, is present in a first switching state of the first switching device and is interrupted in a second switching state of the first switching device. The safety device has a second switching device. An electrical connection of a second energy supply unit of the motor vehicle, which is connected in parallel to the first energy supply unit and is designed as a capacitor, to the at least one electrical component is present in a first switching state of the second switching device and is interrupted in a second switching state of the second switching device.
